PHILIPPINE MACROUROID FISHES GILBERT AND HUBBS. 427 



e\ Snout less than twice as long as orbit ; 4 to 6i scales in a series 

 from origin of second dorsal to lateral line ; first dorsal not 

 black distally; species of the Japanese and East Indian 

 faunas. 

 f. Snout about as long as orbit; species of the Japanese fauna. 

 g\ A scaleless ventral fossa present, between ventrals, sepa- 

 rated by a scaly bridge from the peritroct ; pyloric caeca 

 19 to 23; pectoral longer and stronger, with 17 rays; 

 orbit longer than postorbital length of head; body with 

 a large round spot above and behind pectoral, and another 



below anterior part of second dorsal Mshinouyei. 



g\ No scaleless ventral fossa ; pyloric caeca 25 to 31 ; pectoral 

 shorter and weaker, with 14 to 15 rays; orbit shorter 

 than postorbital length of head ; body with a smaller an- 

 terior spot and no posterior spot jordani. 



f. Snout decidedly longer than orbit ; species of the East Indian 



fauna. 1 



h\ A scaleless ventral fossa extending from between ventrals 



to the peritroct, widest anteriorly ; dorsal spine produced 



into a long filament. 



i\ Dorsal contour of snout straight ; sides of snout strongly 



and evenly convex, without prominent anterolateral 



angles; color darker, the two posterior saddle-like 



markings rather indistinct, not ocellated ; ventral rays, 



7; distance from anus to anal, 2.0 to 4.0 in distance 



from anus to ventral. 



f. Five or fewer very strongly spinous carinae on scales ; 



snout longer, its preocular length 2.3 to 2.7 in head ; 



anterolateral region of snout naked; interorbital 



broader, its least width 1.3 to 1.6 in postorbital; 



body more slender, its greatest depth 1.8 to 1.95 in 



head; color darker, rays of first dorsal light near 



base , maculatiis. 



f. Five to 11 much smoother carinae on scales; snout 

 shorter, its preocular length 2.75 to 2.95; antero- 

 lateral region of snout largely prickly; interorbital 

 narrower, 1.55 to 1.85 in postorbital ; body more ro- 

 bust, its greatest depth 1.6 to 1.7 in head; color 

 lighter ; rays of first dorsal dark near base— velifer. 

 i'. Dorsal contour of snout concave; sides of snout not 

 .strongly convex, with prominent anterolateral angles; 

 7 to 12 carinae on scales; least interorbital width 1.55 

 to 1.85 in postorbital ; greatest depth of body 1.7 to 1.9 

 in head ; color lighter ; first dorsal whitish proximally. 

 k 1 . Tho -two posterior saddle-like markings rather indis- 

 tinct, not ocellated; pectoral rays, 14 or 15; ventral 

 rays, 6; anterolateral portion of snout with a few 

 scales posteriorly; scaleless ventral fossa longer, 

 extending forward to between front of ventral bases ; 

 preocular length of snout 2.48 to 2.6 in head ; preoral 



1 xMany diagnostic details, especially in characters of the head scales, the coloration, 

 etc., are not included in the key, but may he found in the body of the descriptions.
